VAPOR-BU RN ER.

SPECIFICATION forming part of LettersPatent No. 515,424, dated February 27, 1894. Applioationiiled January 19, 1893. Serial No. 458.944. (No model.)

To all whom it may concern:

Be it known that I, JOHN A. CHANDLER, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Vapor-Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

4My invention relates to improvements in burners, for transforming inflammable oils to vapor, then consuming said vapor by combustion, for heating, cooking and other analogous purposes; and the object of my invention is tov produce a burner, whereby the oil is conducted up through the vapor bowl, and over the flame surface thereof, Where it is immediately converted into vapor; thence guided and discharged into the interior ot' the vapor-bowl, Where escaping through the burner-cap, it is immediately ignited.

A further object of my invention is to produce a burner, the drip-cup of which is located Without the vapor-bowl, and convenient of access at all times, and also to produce a burner which shall possess the maximum degree of vapor and heat producing power, with a most economical consumption of fuel; and a still further object is to produce a burner of simple, strong, compact and inexpensive construction.

To the above purposes my invention consists in certain peculiar and novel features of construction and arrangement as will be hereinafter described and claimed.

In order that my invention may be fully understood, I will proceed to describe it With reference to the accompanying drawings, in Which- Figure 1, represents a perspective view of a vapor burner, embodying myinvention. Fig. 2, represents a vertical central sectional View of the same, taken on the line .22 of Fig. 1. Fig. 3, represents a side elevation of the dripcup detached from the vapor-bowl, and showing a portion of the generating tube with its connections, in their proper positions relative to the drip-cup. Fig. 4, represents a plan view in detail of the detlector plate located within the vapor-bowl. Fig. 5, represents a detail perspective view of the switch-lever for guiding the oil'to the drip-cup.

In the drawings, 1 designates the stand-pipe which is connected in the usual manner to the supply pipe from the oil-reservoir, (not shown) which is located in any convenient position.

2 designates the vapor-bowl, which may be of the cylindrical form shown, or of any other desirable form, and which is provided with an opening in its bottom and with a depending fiange or collar 3 surrounding saidopening.

The free eud of the stand-pipe l, is inserted upward through the opening in the bottom of the vapor-bowl a suitable distance, and a set-screw e passing through the flange` 3, secures the vapor-bowl thereon at the desired point. The upper open end of the vapor-bowl is provided with av skeleton burnercap 5, which is of marginal contour to it within the upper end ot said bowl and is composed of cross-strips 5fL arranged a slight distance apart. This burner-cap 5 is provided with an opening vertically over the opening in the bottom of the bowl, andv the depending cylindrical end 7 of a generatingtube 6, is Iitted within said opening andsecured upon the upper end of the stand-pipe 1, which thus communicates Awith the interior of the generating tube. This generating tnbe 6, extends horizontally outward over the burner cap 5, and is formed at its outer end, at a suitable distance beyond the outer side of the vapor-bowl, with the depending tube 8, the passage of which communicates at its upper end with the passage of the generating tube, and at its lower end with the passage of a horizontally arranged tube 9. The forward end of the passage of the tube 9 is formed with a needle-valve seat 10 and a needle valve 11 is adapted to close the saine. This needle-valve 11 is provided with a valve-stem l2 and the usual hand Wheel 13 is carried at its outer end. This valvestem 12 is screw-threaded at 14 to engage the screw-threads 15 in the outer end of the passage ot' the horizontal tube 9. A supporting rod 16 is also formed integral with the said tube 9 and entends vertically downward through an opening in the bottom of the dripcup 17, and is screw-threaded for a suitable distance. Retaining nuts 1S and 19,engage side marginal flanges 22, and at about mid-V way the height of said extension 21, an opening 23 is provided, which is adapted to be directly opposite and a slight distance from the discharge opening of the valve-seat. A waste-pipe 24 also extends vertically upward through the bottom of the drip-cup and near its outer end. A foraminous casing 25 of similar contour entirely surrounds the side walls of the drip-cup 17 and extends upwardly aslight distance above the upper end of the extension 21 of said drip-cup, and within a slight distance of the generating tube 6. This -foraminous casing is provided with an opening 26 registering with the opening 23 0f the extension 2l of the drip-cup, and also with an opening through which the valve-stem l2 extends and operates. A switch lever, approximately Z-shaped is pivoted at 27 to one side of the valve-tube 9, and is provided at kthe forward end of the lower arm 28 with the closing-cap 29 which extends inwardly from and at right-angles to said arm. rlhe up- Wardly extending arm 30 of said lever is of suicient length to extend a slight distance above the upper end of the foraminous casing 25 `and a weight or enlargement 32 is carried at the outer end of the rearwardly extending arm 31 of said switch lever; the tendency of said weight being to hold the closingy cap 29 above the outer end of the tube 9; the object of which will be hereinafter referred to. An opening 33 is provided in the side of the vapor-bowl directly opposite the opening 23 of the extension 21 of the drip-cup, and a horizontal guide-tube 34 is fitted within said opening 33 and extends inwardly of the vapor-bowl toward the stand-pipe 1, and the inner end of said guide tube 34 opens under a curved deliector-plate 35, which rests at its opposite ends upon the bottom of the bowl "and the inner end of the guide tube 34, and is also provided with an opening 3G surrounding.,r closely the stand-pipe 1. This defleetor plate is of concavo-convex form, and of sufficient width to distribute and diffuse thoroughly the vapor over the entire area of the interior of the vapor bowl.

The operation is as follows: When the burner is to be used, the valve 11 is opened, and the weighted end of the switch lever elevated, so that the closing-cap at the forward end of said lever will be opposite to and close the opening 23 in the extension 21 of the drip-cup; the oil is now allowed to How from the reservoir up through the stand-pipe 1, thence through the generator tube 6 and tube 8 into site to the end of the valve-tube 9 is closed by the closing cap 29 of the switch lever) which is filled with esbestus 37; the asbestus becomes saturated, and any excess of oil in the drip-cup escapes through the waste-pipe 24. It will be seen that the solid or non-foraminousextension 21, andthe side flanges 22 thereof, will cause any oil coming in contact therewith to drain into the drip-cup, and not es` cape or be wasted, asit would were the extension and the iianges foraminous. Alightedl match is now applied to the saturated asbestus and the quantity of oil therein burns a sufficient time to thoroughly heat the valvetube and the vertical tube 8 andthe oil therein is generated into vapor; the weighted switch-lever is now released and assumes its normal position, as shown i n Figs. 1, 2 and 3, thus raising the closing-,cap 29 from opposite the opening 23 of the extension 2l, and allowing the generated vapor therein to be discharged from the valve -tube through the opening 23 and intothe vapor-casing through the guide-tube 34. The vapor now thoroughly mixes and commingles with the air within the vapor-bowl, and is then lighted by applying a name to surface of the burner-cap, where the combustion takes place; the flames now impinging against the generator tube 7 thoroughly vaporize the oil passing therethrough. This vaporization of the oil in the generating tube 6, and its discharge thence as vapor into the vapor-bowl where it is mixed with air for combustion, continues as longas the oil from the reservoir is allowed to How.

From the above description, it will be seen that I have produced a burner, which utilizes the maximum of heat producing power to thoroughly generate the oil into vapor, thereby resulting in an economic consumption of fuel, and also a burner which is simple, strong, compact, durable and inexpensive of construction.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a vapor-burner, the combination with a bowl having a burner-cap upon `its upper end, and an opening in its side, of a generator-tube having a valve-tube having its discharge end opposite the opening in the side of the bowl, and a drip-cup containingan absorptive material, and also having an upward `extension or arminterposed between the discharge end or nozzle of the valve-tubeand the opening of the bowl, and a drain-pipe communicating with the drip-cup, and a lever having a closing-cap at one end and aweight at the other end, pivoted to the valve tube and arranged so that the closing-cap may be interposed between the nozzle of the valve- IIO 515,424 l K e tube and the opening in the extension or arm of the drip-cup, to close said opening, substantially as set forth.

2. In a vapor-burner, the combination with a howl or casing having a burnerfcap and an opening in its side, of a valve-tube having its discharge end opposite the opening in the side of the casing and having a valve, and a dripcup having an arm or extension provided with an opening opposite the discharge end or noz zie of the valve-tube and the opening of the bowl or casing, and a foraminous casing surrounding said drip-cup and extending upwardly above the valve-tube, and having an opening for the valve-'stem and an opening registering with the opening of the dripcup extension and the openin g of the bowl or casing, substantially as set forth.

3. In a vapor-burner, the combination with the burner having an opening in its side, of a drip-cup, and a val ve-tube having its discharge end or nozzle opposite said opening, and a switch-lever pivotally carried by the valve-tube and having a closing-cap at one end adapted to deect the oil from the valvetube to the drip-cup, and a Weight at the outer. end of said switch-lever adapted to automatically move the closing-cap from its position opposite the discharge end of the tube, suhstantially as set forth.

4. In a vapor-burner, the combination with a bowl or casing having an opening in its side, a stand or supply -pipe passing vertically through the bowl or casing, and a conveyertube having its outer end communicating with the opening in the side of the bowl and having its inner end adjacent to the stand-pipe, and a valve-tube connected to the stand or supply-pipe, and having its discharge end opposite the outer end of the conveyer-tube, of a concavo-convex deiector-plate arranged obliquely so that its concave side is opposite the inner end of the conveyor-tube, and one end rests upon said tube and the other upon the bottom of the bowl, and also having an opening fitting around the stand or supply-pipe, substantially as set forth.

Intestimony whereof I affix my signature in the presence of two Witnesses.
